7 '0 all whom it may concern:

Be it known that I, FRANK'BOGGS, a citizen of the United States,residing at Atlanta, in the county of Steuben, State of New York, haveinvented certain new and useful Improvements in Double-Belt Potato-Sorters; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to sortingapparatus and more particularly tofruit and vegetable sorters, and has for its object to provide a sorterincluding a series of separating belts,-one within the other, to effectthe separation of severaldiiferent sizes of potatoes or othervegetables.

Another object is to provide means for delivering the sorted vegetablesfrom the machine in an ellicient manner. Another object is to providemeans for moving the belts which will include drums so constructed 'asto be ad'ustable for different belts and also so ma e as to facilitaterepairs,

Another object is to provide guide rolls to promote the ease ofoperation of the device and also to provide an improved belt for use in'conjunction with such rolls.

Another object is to provide means for varying the tension of the belts.

In the drawings: Figure 1 is a side elevation of the complete machine.Fig. 2 is a top plan with the belt removed. Fig. 3 is a verticalsectional view 'taken centrally and longitudinally through the machineshown in Fig. 2. Fig. -l is an end View. Fig. 5 is a transverse sectionon line 55 of Fig. Fig. ('3. is a fragmentary perspective view of thebelt. Fig. 7 is a perspective view of the angular driving drum. Fig. 8is a detail showingone of the guide rolls and its mounting. v

Referring now to the drawings, the present invention comprises aframeincluding side walls 9 and 10 between which, at one end, there ismounted an angular driving drum of peculiar construction to be laterdescribed, the drum .beiu indicated .at 11. At the opposite end of theside walls a cylindrical drum 12 is mounted thcrebetween and between thetwo drums there are a plurality of transverse angular supporting rolls13, pivotally mounted.

The frame is supported by forward legs ll adjacent to the drum l1 and byrearward legslfi adjacent to the drum 12.

A hopper 16 is mounted upon the side walls 9 and 10 at the rearward endof the machine and just forward of the drum l2.

Forwardly of the legs 15 there are a pair of supplemental legs 17,opposite each other Patent-ed Apr. 2o, was.

transversely of the machine and betweenv these supplemental legs thereis pivoted a transverse tension roller 18, arranged rmadjustmentvertically of the supplementallegs.

- Engaged around the drums 11 and 12 and beneath the drum 18 there is aseparating belt 19 of the structure disclosed in my issued Patent No.1,032,375, but including a modification to be later described. This beltrests upon the rolls 13 which, being angular, agitate the belt as itpasses-thercover.

As set forth in the issued patent referred to, the belt is composed of aplurality of i1 terwrwen pieces of wire, each formed into loo 3s 20having parallel arms 21, the arms of the adjacent loops being connectedby small vertical loops 22, the arms of the adjacent loops lying oneabove the other. In the complete belt the small loops 22 of one of thepieces of wire are engaged centrally of the large loops of the adjacentpiece of wire, there being thus formed a plurality of substantiallyshield-shaped openings through the belt, and the structure resulting ina plurality of transverse pivotally connected sections A. Themodification of the original 1 structure of the belt,,referred to above,lies in the treatment of the free ends of the wires at the sides of thebelt. In the present structure one free end of each section terminatesin one of the small loops 22, as in the original issued patent, but theopposite free end is carried through the small loop 22 in which it isengaged, as shown at and is then carried away from this loop,rearwardl'y, to a point adjacent the terminal large loop 20 of the nextsection, where it is bent inwardly toward the center of the belt asshown at 24.

Toprevent' any drag interferin with the movement of the belt around therums and rolls, incident to engagement of the edges of the belt with thesides of the machine, there are provided guide rollers 26, these rdllersbeing mounted in openings 27 formed in the side walls 9 and 10, theseguide rolls being mounted upon vertical pivots 28 which are openings .32in the straps, above which suitthat the straps may be held at differentpoints of their pivotal movement. This per-f mits of movement of theguide rolls 26,170; ward and away from the edges of the belt and it willbe observed that the structureof the belt, which includes themodification above set forth. makes it possible to employ these guiderolls, when such use would be impossible if the edges of l7he belt didnot present substantially unbroken lines.

A guide roll 34, similar to the rolls 26 and correspondingly mounted isconnected with each of the rearward legs 15 to engagethe edges of'theupwardly extending portion of edge "just roarwardly o'l' tl I thebelt between the drum 12 and the ten- 25 sion roller 18.

Wholly within the inclosure of the belt 19 there is a similarly madebelt 35 but of smaller mesh, and this belt is mounted on a rearwardcircular drum 36 mounted between the side walls bGlOW 'thQ drumlfl andalso upon a second angular driving drum 37 lo catcd below and rearwardlyof the driving drum 11. This second belt 35 .is supported by transverseangular rolls 38 mounted be tween the side walls and it also extendsaround a second tensioning roll 39 mounted for vertical adjustmentbetween the legs 17 above the roll 18. l

Secured between the walls 9 and 10 forwardly of the drum 37 there is achute 4.0 leading out at the'side of the machine below one of the sidewalls, this chute being adapted to receive from the forward end of thebelt 35 where is passes over the drum 37. -A second chutedl is mountedbetween the .side walls beneath the upper portion of the belt 35 at therearward end thereof, and a suitable apron 42 exthnds from the forwardof this chutc I! to a-cross bar 4-3 which is mounted between the sidewalls 9 and 10 to drum 37.

crank is provided for the rotation of the drum H and suitable drivingconnectionsextcml between this drum and the-drum 37 for movement of thetwo drumsvsimule tancously in the same direction.

The two drums 11 and 37 an angular core '14 having secured to each m":its faces :1 slat 45 which projects beyond the next face, and theseslats are adjustable to I pro ect different distances beyond the faces.sections A of different of the core so the free edges be understood,

as to adjust the space between of the adjacent slats, as will tocorrespond to belts having widths. The slats able nuts 33 are engagedwith the bolts so tables upon the be Guide rolls 46 are of a series ofinter each consist of illustrated so as belt when they have becomeabraded.

In operation, fed into the hopper 16, fallin upon the upper portion ofthe belt 19;

vegetables to be sorted are he drum 11 is.

rotated to move the upper portion of the belt forwardly, when thesmaller vegetables will pass through the belt, falling upon the secondbelt 35 and the larger vegetables will pass from the forwardend of themachinetaclel Therlarger vegert 35 will be discharged into a suitable rtherefrom into the'chute 40 and the smaller vegetables-will pass throughthis belt and will be discharged from the chute 41.

provided for the edges of the second belt 35 and are mounted similarlyto the rolls 26, that the upwardly, extending portions of both belts areclose together ,so. as to be guided by the sin le pair of rollers 34.

What is claimed, is':, 1. In a separating machine, a flexible beltformed of a series of connected sections, a drum for impart-in avibratory motion to the belt and inclu lug-projecting members adapted tocontact with the belt at the points thereofwhe'r'e nected, and-means foradjusting said members tomaintain the latter in contacting relation.with such points of the belt irrespective and it will be observedthesections'are con- 7 s 1' of the shortening or lengthening of thebelt. 7

In a separating machine, a belt formed for imparting a vibratory motionto thebelt including projecting members adapted to contact with the thestrands interloop, ingsaid members to contacting relatio portions of thesti h riations in the length ofthe belt.

' 3. In a separating machine, abelt formed oi. a series ofiinterloopingwire strands, one terminal of'each strand being an eye to engage withthe end loop of an adjacent strand, the opposite terminal of each-strandbein free from connection with the end loop or the adjacent strand, saidand means IOI' adjustmaintain the latter in with the interloo ingfree'end being turned inward, the construc-' tion being such that theassembled loops present substantially continuous edge portions, andguiding means adapted to be uniformly engagedfiy the substantiallycontinuous edge portions of the belt.

In a separating machine, a sorting belt comprising a plurality oflengths of wire,

ooping strands, a drumbelt at the po nts where nds irrespectiveo va aprovided with each length being formed into a series of i loops, theconnecting portions of the loops of one length of wire being engagedwith the loo s o the adjacent length of wire, the ends 0 each lengthofwire terminating near the adjacent length to unbroken edges for. thesorting belt.

produce substantially o a sortmg' t e aging wit 0 ums "andcompnsing afiurahty of interwoven 5 lengths 'of wire,:eac formed into loops havingparallel arms, the arms of the adjacent loops'of each ,length lying oneabove the other, said wires at the; ends of the arms being bent to formsmall connecting loops, 10 .said small loops of onelength bemg engagedcentrally of the large loops of the next adjacent length, one end ofeach length of wire being engaged through a small loop of one adjacentlength, and then carried away from said smal loop to a int adjacent theterminal of the large l' d p of the other adjacent length, and thenturned inwardly of the element, and gqide devices carried by the framefor engagement with the edges of the belt.

In testimony whereof, I afiix my signature, in the presence of twowitnesses.
